What's the best hygrometer out there?

I change batteries regularly and they've done me just fine so far.

I have the same.. Been perfect for me.. No complaints..

This is what I use:

I like it because it is wireless so I can monitor my humidors without opening them. Once I calibrated them, they have been spot on.

I've had good luck with the Hygro-set rectangular ones.

POWA UP!!! I have a few Caliber IV's that are awesome & 1 Caliber IV R that was on-point as well! I really wouldn't go with anything else at this point- unless you're looking for more features, like wireless or having a system of a few set up to one monitor. At that point I've heard that these are pretty cool:

and

But if you want to be super-real about it, get a NIST one if that will make you feel "more certain". Frankly though, I'm not going to bother.

I'll echo the Caliber IV recommendations. I own six of them, plus an older Caliber III. None were more than two points off at either 75% or 65% (both tests using Bovedas), and the Caliber IV is adjustble up to six points plus or minus. About $25 most places, but I've seen them for $20 on occasion. They use the common CR2032 button cells (about the size of a quarter), and should last six months to a year or longer; if your reading seems to be off, it's probably a battery near the end of its useful like. (I buy CR2032s in five-packs and keep spares on hand.)
